DAVON s.r.o. is a Czech manufacturer of jaw crushers, cone crushers and complete mineral processing equipment, supplying mining and quarry clients across 29 countries with full ISO and safety certifications.
Original imported split cone bearings suffered roller chipping, inner-ring cracking and dust seizure, requiring replacement roughly every 4 months with 45-day import lead times.
Provide domestic high-impact-resistant bearing alternatives raising service life at least 1.8x, cutting procurement cost and 45-day lead time, surviving dusty rainy pits—all without altering existing crusher mounting dimensions.
Ore collisions create pressure spikes causing roller-edge chipping and inner-ring fatigue cracking.
Gravel dust and rainwater invade unshielded positions, triggering internal rust and seizure.
Spindle housing dimensions cannot change—only internal structure optimization is allowed.
Unplanned maintenance halts the full line, demanding at least 1.8x longer bearing life.
Forged high-chromium steel with enlarged roller-end arcs and reinforced chamfers disperse impact stress.
Labyrinth plus skeleton oil seal with high-temp waterproof extreme-pressure grease blocks infiltration.
Widened windows and limit flanges stop roller displacement under violent shock loads.
Dynamic impact simulation and full load bench testing with official reports before shipment.
Custom 352240X2 bearings ran 9 consecutive months on aggregate lines with no cracking or seizure; monthly shutdown hours fell 70%, and DAVON terminated all overseas orders to sign an annual bulk-supply framework contract with EGEN.
